The traditional SPF routing limitations are analyzed and the traffic engineering concept is given. MPLS, resource reservation protocol (RSVP) and enhanced link status Protocols intermediate system to intermediate system (IS IS) are reviewed to provide a background for traffic engineering, the general issues of designing an MPLS system of IDC network for traffic engineering are then discussed. Finally a practical example with MPLS traffic engineering is shown.展开更多

It combines the induced learning based-on decision-making tree with the blocking neural network. And it provides a useful intelligent knowledge-based data mining technique. Its core algorithm is ID3 and Field Theory based ART (FTART). The paper introduces the principals of hybrid machine learning firstly, and then applies it into analyzing family apparel expenditures and their influencing factors systematically. Finally, compared with those from the traditional statistic methods, the results from HML is more friendly and easily to be understood. Besides, the forecasting by HML is more correct than by the traditional ways.展开更多

The processed data come from experiments and numerical simulations. In comparison with a Fourier transform, the POD gives the best modal approximation for both initial fields, in terms of the energy expressed on any given number of modes to be taken into account： to reach 98% of the total energy of the velocity field, the required number of POD modes is around nine times smaller than the number of Fourier harmonics. The individual POD modes are given and show that the unsteady rotor-stator interaction is already present in the very first modes.展开更多

Methods： A total of 152 subjects were randomized in visit sequence into two groups： a treatment group in which 76 cases were treated by application of Jiao Tai Pill on point Shenque （CV 8） and a control group in which 76 cases were treated by oral administration of Jiao Tai Pill, both with a course of four weeks. Pittsburgh Sleep Quality Index （PSQI） was used to evaluate the clinical efficacy respectively before treatment, at one-week, two-week and four-week treatment, and one week, two weeks and four weeks after treatment. Results： After four-week treatment, the sleep quality had improved in both groups, with no statistical difference between the two groups; there was no side-effect and the sleep quality kept improving thereafter. Conclusion： Application of Jiao Tai Pill on point Shenque （CV 8） and oral administration of Jiao Tai Pill both have positive effects on insomnia and no apparent withdrawal reaction after treatment.展开更多
